iinother object of the invention is to proand adapte to be rolled up on a roller or vide a windowshade construction having a similar construction designated at 11. The pair of slats forming the shade stick between shade stick at the bottom of the shade is which the fabric forming the window shade formed of two slats 12 and 13 having horiextends which employs end staples which are zontal bottom surfaces and vertical inner driven into the ends of the slats for fastening surfaces. The outer sides of the slats conthe slats and fabric together and which emverge upwardly toward each other, both with ploys a hollow rivet passin through the slats respect to each other and with respect to the at the center thereo whic hollow rivet not inner surfaces on their respective slats. The only fastens the slats and fabric together but fabric 10 extends downwardly between the also provides for the reception of the shade slats 12 and 13 and is reversely bent upon its cord. self as indicated at 14 between the slats with Another object of the invention is to prothe end of the fabric extending upwardly bevide a novel folding of the fabric so as to entween the slats bent around the top of slat 12 close the slats and present a finished surface as indicated at 15, downwardly over its outer thereon. side as indicated at 16' beneath the bottoms of -With the foregoing and other objects in the two slats as indicated at 17 then upview which will be made manifest in the folwardly over the outer side of slat 13 as indilowing detailed description and specifically cated at 18 and finally downwardly between pointed out in the appended claims, reference the slats terminating as indicated at 19 near ing the bod or major portion of the shade I "the reverse bend 14. In this manner the fabric 1O suspends the curtain stick formed by the two slats from its center and also forms a finished surface over the outside of the two slats. A method of assembling the fabric and slats is represented by Fig. 5 wherein the two slats 12 and 13 are laid on the fabric 10 near its bottom edge with the lower end of the fabric bent over against the interior surface of slat 13. A tuck or pleat is taken in the fabric 10 forming the reverse bend 14 and this tuck or pleat is laid a ainst the interior surface of slat 12. Suita 1e means for fastening the fabric to the slats may be employed, such as metallic staples 20 driven throughthe fabric into the interior surface of slat 13 and through the reversely bent portions of the fabric into the interior surface of slat 12. It will be noted that the staples or equivalent fasteners 20 are not long enough to projectthrough the slats. After the fabric is thus fastened to the slats the slats are folded upwardly against each other from the position shown in Fig. 5 to the position shown in Figs. 2 to 4 inclusive.

, A feature of the invention resides in then fastening the slats together so that they will clampingly engage upon the fabric and so that the finished surface provided by the fabric 10 on the outside of the slats will not be marred. This is accomplished by forming a hole 21 through the slats and fabric at the center of the slats and fastening therein a hollow rivet 22. The hollow rivet thus fastens the slats and fabric together and provides for the reception of the shade cord 23. As it is conventional to use some form of hollow rivet or grommet to receive the shade cord the use of the hollow rivet for this purpose does not mar to an undue extent the finished surface on the outside of the slats. The hollow rivet 22 thus fastens the slats toether at their centers and the slats are also astened together at their ends. This is accomplished by means of sheet metal staples 24 which have their sides converging upwardly and inwardly bent prongs 25 which are driven into the slats 12 and 13. These staples connect the slats together at their en s and maintain them in clamping engagement upon the fabric 10. By virtue of the fact that they are driven into the ends of the slats they do not mar or detract from the finished surface provided by the fabric 10 over the outside of the slats.

In Figs. 7 and 8 there is disclosed a novel manner for enclosing the slats 12 and 13" by the fabric 10. .The slats 12 and 13 are laid in parallel relation near each other and near'the end of the fabric 10. The end of the fabric is then bent over against the interior surface of the slat 13 and then is extended beneath the outer surface of slat 12, finally terminating as indicated at 26 abouthalf way down from the top of the interior surface of slat 12. The fabric 10 is then given the pleat .or tuck to provide the reverse bend 14 and this pleat or tuck is positioned over the end 26 against the interior surface of the slat 12. Staples or equivalent fasteners 20 are then driven through the fabric into the interior surface of the slat 12 driven through the fabric into the slat 13. After the staples 20 have been driven the slats are folded upright with the slat 13" shifting the required amount or partially turning within the loop formed by the fabric 10 enclosing it. When the two slats assume the upright position sideby side as shown in.

Fig. 7 the hollow rivet 22 and the staples 24 may then be driven into the slats fastening them and the fabric together. l

From the above described construction it will be appreciated that a novel and advantageous window shade construction is provided wherein the stick of-the'shade presents a uniform, neat and attractive finished surface which is not marred nor detracted from by nails or equivalent fasteners which'have 1.
